title: The effect of pulmonary root translocation on the left ventricular outflow tract.
abstract: We report the effect of pulmonary root translocation on the left ventricular outflow tract. A double switch operation with pulmonary root translocation was performed in a 6-year-old boy whose diagnosis was dextrocardia, congenitally corrected transposition of the great arteries, ventricular septal defect, and pulmonary stenosis. Postoperative magnetic resonance imaging showed more natural left ventricular outflow than preoperatively (19 mm vs 22 mm in length between the top of the interventricular septum and the aortic valve). This technique does not require coronary transfer and enables preservation of the aortic root structure. The long-term results, including left ventricular outflow tract morphology, should be evaluated.
